Influence of Seismicity Level on the Induced Response and Cost of RC Buildings in Saudi Arabia

The current research aims to study the influence of seismic regions on structural design and construction management of Reinforced Concrete (RC) residential mid-rise buildings to gravitational and seismic loads. Three cities in Saudi Arabia, (Dammam, Jizan and Faifa), of different seismic intensities are selected. Static and dynamic analysis, in terms of Equivalent Lateral Force (ELF) and Response Spectrum (RS) are used respectively to perform the seismic calculations needed for designing horizontal and vertical structural elements. The analysis is performed using the available structural software package ETABS and the design is implemented following the requirements of ASCE-7-16 and ACI-318-19 Codes for loads and structural concrete respectively. The management components of the project are taken into consideration concurrently with the analysis and design phases of the project in order to guarantee that the building will be constructed promptly and at an affordable cost. The inquiry considers the planning of the project, the take-off of the quantity, and the control of the project as essential management components. The results show that the seismic response of a typical RC building, in terms of base shear, and story displacements, change significantly due to the change in seismic region. Results from construction management point of view indicate that seismicity level substantially influence the needed materials for construction, time duration, and cost of the performed project.
